. . . INTRODUCTION

One of the hnc t ions of the State Ehgineer i s the administration of the

laws and regulations re la t ing to the appropriation and use of our ground-water

resources, Ground water can be compared with money on deposit i n a bank, Aa

long as deposits exceed o r equal withdrawals, a working balance oan be main-

tained. I f withdrawals should exceed deposits, the bank account i s depleted,

and if t h i s practioe i s continued, the money on deposit i s eventually exhausted.

I f the annual withdrawal of ground water from a ground-water reservoir exoeeds

the amount of annual recharge, there wil l be a reduction in the mount of ground

water i n storage and a corresponding lowering of water levels. The annual

appropriation of ground water i n excess of annual recharge i s tenned "ground-

water mining",

The State k g i n e e r has carried on a program f o r the measurement of ground-

water levels f o r many years i n cooperation with the Ground Water Branch of the

0. 9. Geological Survey. This program was expanded i n 1962 and the task of

measuring water levels was assumed by the State Ehglneer. This report presents

hydrographs of wells located i n many of the la rger ground-water basins. These

hydrographs show the extent of ground water depletion during periods of with-

drawal and the extent of reoovery during recharge periods and serve as an early

warning system to depict areas where problems of ground-water supply a re l i ab le

t o develop.

To date, Oregon has very few serious problems of ground-water miniwe Two

areas have been determined as being "cr i t ica l" on the basis of declining water

levels. These are the Cow Valley area +n Northern Malheur County and The Dalles

area i n Wasoo County. Both of these areas have been closed to fur ther appropri-

a t ions except f o r stock and domestic pu$poses. Both of the orders of the State

Ehgineer determining these areas as beirlg "cr i t ica l t t have been appealed to our

courts t o deternine the oonstitutionaliiiy of Oregon's Ground Water Act.

There have been some water level ddolinea i n the deep wells i n the Ordnance-

Hermiston area and the Milton-Freewater rarea during the past few years. New

observation wells are being established &n th ie area t o determine the extent and

ra te of these deolines.

GROUND WATER INVESTIGATION

Ground-water inveetigations by the $tate h g i n e e r were being carr ied out i n

the Salem Hills area of Marion County, the westside business d i s t r i c t in Portland,

and The Dalles area i n Wasoo County. The4 U. S. Geological Survey, working

financial cooperation with the State E n w e e r oarried on inveetigatione in the

French Prairie-Mission Bottom area of Marjion County, the Salem-Molalla Slope area

of Marion and Clackamas Counties, and the Eola Hills-Amity area of Polk and Y a m h i l l

Counties. Reoent reduction i n State fundg f o r ground-water inveetigstions hae

caused a eerioue reduction i n this ooopergtive program.

OBSERVATIO$ WELL PROGRAM

The observation well program consist# of the periodic measurement of the

depth t o water o r ar tesian pressure i n watler wells looated throughout the State.

A t the close of the year, the observation well net had been expanded t o 715 wells

located as follows:

Appreciation i s also given t o the many well owners of the State who have cooperb

ated i n making t h e i r wells available f @ r measurement i n this program.

WELL NUMBEUNG SYSTEM

The well numbering system used i n t h i s report gives the township, range,

section and 40-acre subdivision of the aeotion i n which the well i s located. The

f i r s t number i s the township, and the ~econd number i s the range. In townships

lying south of the Willamette Base Lin$ and i n ranges lying eas t of the Willamette

Meridian, the l e t t e r s "Sw and "En are Qmitted. The number following the hyphen

indicates the section and the l e t t e r ilpdicates the subdivision of the seation as

depioted i n the following diagram. The number i n parentheses following the l e t t e r

i e the s e r i a l number of the well.

For example, the well numbered 27117-22~(2)

indicates the well i s i n the SE$4 SE%, section 22,

Township 27 South, Range 17 &st, and $8 the second

well noted i n t h i s 40-acre t ract .

TUALATIN VALLEY (1)

PORTLAND METROPOLITAN M&A (2)

The westside business d i s t r i c t of Eortland i s one of the most concentrated areas of large ground-water developments i n the Fortland Metropolitan Area. Ground water i s used f o r heating and cooling of mamy of the l a rge o f f i c e buildings.

The westside business d i s t r i c t i s w d e r l a i n by water-bearing a l l u v i a l sand and gravel deposits and the Columbia R i v ~ r Basalt Fornlation. The water-bearing gravels a r e separated from the underlyinp basa l t by a sect ion of s i l t and c lay known as the Sandy River Mudstone. Welle develop water from both the gravels and basalt . Owing t o sewer charges, operators have constructed recharge "3 ;. ' wells f o r the disposal of waste water. ome operators pump water from the basa l t and dispoae of water i n the gravels and borne operators pump water from the gravels and dispose of water i n t o the basalt . This seasonal t r ans f e r of water from one formation t o another and di f ference i n weter qua l i t y and water temperature has created a very complex hydrologic conditton. To date, most of the observation wells i n the metropolitan a rea have been concentrated i n t h i s a rea t o a id i n the evaluation of t h i s pyoblem area.

THE D-8 AREA (3)

The area in and around Dalles City has been declared a "Critical Ground Water Area" because of declining water.levels, The ground-water reservoir developed by most of the mioipal, in4ustrial and irrigation well8 develop ground water from a very permeable zone in the Columbia River Basalt Formation. This zone has been named The Dalles Grqund Water Reservoir and is looally known "The Dalles Pool", The 1963 spring hieh position of the water level in The Dalles Ground Water Reservoir was at arl altitude of about 44 feet or some 29 feet below the adjacent level of the Bqnneville pool in the Columbia River. Without a reduotion in ground-water wifhdrawals or an increase in ground-water recharge, ground water levels in The Dellee Gmund Water Reservoir will continue to decline,

A slight decline has also been observed in the confined ground-water reservoir located in the Mill Creek Valley, (1~/12-13~(1) and the rate of deoline in the Three Mile Creek Valley has decreased (1~/13-14~(1),

MILTON-FFWh'ATEH AREA (5 )

Milton-Freewater is located at the head of a large alluvial fan where the Walla Walla River flows out of the Blue Mountains. This fan which is in large part composed of coarse gravels is reoharged by the Walla Walla River and by irrigation diversione. High water level in many of the wells occurs during the irrigation season.

The alluvial fan is underlain at depth by the Columbia River Basalt Foma- tion. Some of the deep wells in the Milton-Freewater area, which develop ground water from the basalt, have been declining in recent years. New observation wells are being established to learn nore about this decline.

GRANDE RONDE VALLEY (6)

The Grande b n d e Valley i s a broad, deep, s t ruc tura l valley tha t has been pa r t i a l ly f i l l e d with lake and stream deposited clays, silts, sands and gravele. The coarse-gralned sand and gravel deposits are confined chiefly t o the a l luvia l fans that have formed where the la rger streams flow in to the valley. The deeper materials i n the basin f i l l are chiefly fine-grained si l ts and clays.

The basin i s underlain by the Columbia River Basalt Formation which contains confined ground water. Wells d r i l l ed into the basalt generally flow at the sur- face. Many new i r r iga t ion wells have been d r i l l e d during the past year. Some of these develop eeveral thousand gallons per minute from the sand and gravel deposits. New observation wells a re being established i n t h i s area t o evaluate the e f fec t of these new ground-water developments.

GOOSE BASIN

The Goose Lake Basin is a l a rge s t ruc tu r a l basin located i n southeastern Lake County. This basin has been p a r t i a l l y f i l l e d with stream and lake deposits . The stream deposited sands and gravels occur ch ie f ly where a l l u v i a l fans have been b u i l t i n t o the basin. Some of the a l l u v i a l deposi ts have been buried by fine-grained lake sediments which tend t o confine the ground Water and cause some wells t o flow.

In general, the water t ab l e stands close t o land surface and a large quan- t i t y of ground water i s i n storage i n t h i s basin. Ground-water developments f o r i r r i g a t i o n a r e few i n nurnbcr but ar9 e:cpected t o increase.
